AI Stack

India is anchored in the vision of AI for Humanity and building a robust AI stack is both a technological priority and a social commitment for India.

About AI Stack:

• An AI stack is the complete set of tools and systems that work together to build and run AI applications. 

• It makes artificial intelligence work in the real world, from the apps people use every day to the data, computing power, networks etc.

It is made up of five layers:

Application Layer

• It represents the user-facing component of the AI stack.

• It includes AI-powered apps and services such as health diagnostic tools, farming advisory platforms, chatbots, and language translation applications.

• This layer turns complex AI processes into simple, user-friendly services that people can easily use.

AI model layer

• It acts as the brain of AI systems. AI models are trained on data to recognize patterns, make predictions, and take decisions.

• It is the core intelligence that determines how effectively applications can understand, predict, and respond to real-world needs. 

• Example: They help detect diseases from X-rays, predict crop yields, translate languages, or answer questions through chatbots.

Compute layer

• It provides the computing power required to train and run AI models. During training, compute processes vast amounts of data so the model can learn and improve. 

• It is the critical enabler that determines the scale, speed, and sophistication of AI innovation.

Data Centres and Network Infrastructure Layer

• Data centres are where AI systems are stored and operated, while networks like the internet, broadband, and 5G move data between users, computers, and AI models.

• The data centres and network infrastructure layer provides the foundational backbone that enables AI systems to operate at scale and in real time.
